I dealt with chronic nausea for six years until I was diagnosed with Mals. I didn't v have typical symptoms but the CT scan of abdomen showed some compression. Its been 8 weeks since surgery and feeling better most days. I totally understand what your husband is going through. I sat in my chair and didn't know how to go on. Went to every kind of Dr and many gastros. Don't quit seeking help. Go to different drs.
